1 Claim. 1

The present invention is directed generally to a novel and improvedwagon box elevating and tilting device, but more particularly to asimple portable and improved construction of a lifting device, Whichwill straddle or arch the tongue of a wagon and effectively elevate ortilt the wagon box to desired height, to dispense or dischargesubstantially the complete contents therefrom by gravitation.

The invention further contemplates as one of its objects a new andimproved type of a wagon box lift in combination with a conventionalform of hydraulic jack supported by an arched frame straddling thetongue of the wagon, and at the same time one which is easily attachedto or detached from the front ends of the wagon boxes.

The invention further contemplates as one of its objects a novel supportfor a conventional type of hydraulic jack which may be placed in closeproximity to the swingin forward edge of wagon box with guides providedfor on the jack support to permit a free movement of the swing ing wagonbox without any obstruction.

These and other objects are accomplished by providing a construction andan arrangement of the various parts in the manner hereinafter describedand particularly pointed out in the appended claim.

Referring to the drawings:

Fig. 1 is a perspective view of a conventional wagon and wagon box withthe box in raised or elevated position showing my improved liftingdevice or jack connected therewith;

Fig. 2 is an enlarged fragmentary view partly in cross section showingmy improved lifting device; and

Fig. 3 is a fragmentary front elevational View of the lifting device.

In illustrating one form of my invention, I have shown the same inconnection with a conventional form of farm wagon which includes,briefly, front and rear supporting wheels it and II journaled on theconventional axles and a connecting reach l2 connecting the front andrear structure of the wagon together. The front and rear axle structuresof the wagon are provided with the usual front and rear bolsters orbeams l3 and M respectively. The rear bolster, of course, supports andforms a pivot for the wagon box in a manner well understood in the art.The Wagon box in this instance is generally indicated by the referencecharacter it. The front bolster 13 forms the support for the wagon boxwhen it is in its normal horizontal position, The wagon is provided withthe usual tongue and tongue support, generally indicated by thereference character l1.

My improved lifting device includes an arch support which straddles andextends over the tongue and tongue support of the wagon and is generallyindicated by the reference character l8. This arch support comprises ahorizontal transverse channel member I 9, to the outer ends of which aresecured vertically extending pipes and posts 29. These posts. 20 arewelded to the underside of the channel [9. Secured to the lower ends ofeach of the pipes or posts 2!]; are nonskid discs or cups 22 which areadapted to rest on the ground. Secured to the rear side of the channel I9 adjacent the opposite ends thereof are curved guide bars 23 which havetheir lower ends welded to each of the posts 20 as shown at 24. Theseguid bars 23 are curved or arcuate in shape and have their upper endsprojecting above the channel [9. The guide bars are adapted to engage ahorizontal angle member 25 secured to the lower forward edge of thewagon box I6 50 as to prevent the jack support from obstructing the upand down movement in the raising and lowering of the wagon box. Mountedon the center portion of the top side of the channel member I9 is aconventional post type hydraulic jack, generally indicated by thereference character 26. The jack in this instance is preferably, thoughnot necessarily, of the hydraulically operated type, but other types ofjacks may be employed in connection with my invention. This" jack isprovided with the usual hand operating lever 21 and a vertical tube 28.Reciprocably mounted within the tube 28 is a lifting shaft 29.Telescopically mounted on the post 28 and secured to the lifting shaft29 of the jack is a lifting pipe or telescoping sleeve 30 which issecured to the upper end of the shaft 29 by a nut 30'. Secured to theforward intermediate portion of the sleeve 30 is a vertically extendingsteel strap 3! which has a plurality of uniformly spaced apart apertures32. Any one of these apertures 32 are adapted to receive a rearwardlyprojecting prong or pin 33 which is angularly disposed and secured to aring 34'. The ring 34 embraces the sleeve 30 and the strap 3 I. Formedintegrally with and extending downwardly from the ring 34 is a hook 35which is adapted to engage an angularly disposed eye-bolt 36. Theeye-bolt 36 extends through an aperture in and is loosely secured to theangle member 25 by a nut 3'1. From the above description it will be seenthat the hook 35 and ring 34 may be vertically adjusted to variouspositions in the various interference.

apertures 32 on the strap 3| so as to accommodate a, variety ofdifferent wagon boxes whose height from the ground may varyconsiderably.

Summarizing the advantages and functions of operation of my improvedwagon box lifting and tilting device, it will readily be seen that byproviding an arch support for the hydraulic jack which straddles thetongue of the wagon, the necessity of attachment with the wagon bolsteris not only avoided, but also the jack proper can be placed in closeproximity with the end of the wagon box to more efficiently andeffectively raise the box. In this connection it will also be noted thatthe guide bars on the jack support will permit the free swingingmovement of the'box without obstruction. If the jack and support areplaced too closely in relation to the wagon box, these guide bars willengage the angle member 25 and swing the support and jack forwardly onthe discs 22 and permit the passage of the box without The advantage ofquick detachability of the device from one wagon to another affords avery simple, efiicient and easily manipulated lift for this particularpurpose.

While in the above specification I have described one embodiment whichmy invention may assume in practice, it will, of course, be understoodthat the same is capable of modification and that modification may bemade without departing from the spirit and scope of the invention asexpressed in the following claim.

What I claim as my invention and desire to secure by Letters Patent is:

A lifting mechanism for lifting and tilting a wagon box comprising anarched frame, a lifting jack mounted on said frame having an extensiblemember associated therewith, a telescoping sleeve embracing said lastnamed member and secured to the upper end thereof, a verticallyextending steel strap'secured to one side of said sleeve and having aplurality of vertically spaced apart apertures therein, a ring memberembracing said sleeve, a pin secured to said ring and adapted to engageany one of the apertures in said strap, a hook member carried by saidring and engageable with one end of said box, and a hand operated leverlocated adjacent said arched frame and operatively related to saidlifting jack for raising said wagon box.
